聲明下：本人想把CMakeLists中的內容寫好,csdn格式化了，無能為力，以下是本人在生產環境中已經使用過了。

測試代碼:
#include
int main()
{
//不支持linux
//#ifndef _DEBUG
#ifndef DEBUG
std::cout << “release” << std::endl;
#else
std::cout << “debug” << std::endl;
#endif
}
使用命令
cmake -DCMAKE_BUILD_TYPE=Debug … //編譯出debug版本
cmake -DCMAKE_BUILD_TYPE=Release … //編譯出release版本
以下是CMakeLists的編寫
#Cmake最低版本要求
